Residential ARIN
Summary
Google Fiber
isp telecom infrastructure
Over two million addresses, eighty prefixes, and one netname on all of them.
What it's used for
- A residential fibre provider's network. Eighty IPv4 prefixes and one IPv6 prefix announced from the United States, more than two million addresses, through nineteen observed BGP neighbours.
Notable
- Every listed block carries the same netname: the brand shortened by one word, a hyphen, and a marker for the protocol version.
- The blocks are cut from a single parent range into pieces of four different sizes, announced separately rather than as one.
- Eighty IPv4 prefixes stand against a single IPv6 prefix, which is the whole IPv6 announcement.
- All eighteen queried addresses answered, every one the address with hyphens on the brand's own domain. There are no exceptions and no second pattern.
- Nineteen observed neighbours carry the whole thing.
Interesting
- A hundred per cent answer rate across two million addresses is a generated zone with no hand edits in it. Every address has a name whether anything is using it or not, which is the only way to name a network this size.
- A version marker in the netname on a record with one IPv6 prefix reads as an intention. The field distinguishes something the address space has barely begun to need.
- One name across eighty prefixes is the opposite of most large records, which accumulate a netname per acquisition. This space was requested once, by one company, for one purpose, and the paperwork never had to absorb anybody else's.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
